Unformatted text preview: Electrons have equal chance of absorbing photon: à༎ Max KE of electrons = photon energy - Φ à༎ Min KE = 0 à༎ Some electrons, not enough energy to pop- out, energy into heat. 29 Electrons over large range of energy have equal chance of absorbing photons. Electron potenHal energy Ephot Ephot work funcHon Φ Inside metal You iniHally have blue light shining on metal. If you change the frequency to violet light (at same # of photons per second), what happens to the number of electrons coming out? a. fewer electrons kicked out b. same # of electrons c. more electrons kicked out d. not enough informaHon 30 Electrons over large range of energy have equal chance of absorbing photons.
